Notes for new Users:

SIM7000/SIM707G does not support a 4G network. Please ensure that the USIM card you use supports 2G(GSM)/NB-IOT access, SIM7070 positioning and cellular cannot be used simultaneously. Please disconnect the network when positioning, and turn off GPS when connecting to the network

pin VIN is a USB input; if a battery is being used to power the device, there will be no voltage output from VIN, meaning 3.3v is the only power output.
When using the built-in battery pack the on/off switch will function as normal, supplying/cutting off power to the board, However, if an external battery pack is used and attached to the VBAT pin the on/off switch will be bypassed meaning the only way to shut off will be to disconnect the batteries.
On/off switch is for battery use only, it will not function when plugged into USB.
Battery voltage can not be read when plugged into USB using the onboard BAT ADC(35)
Recommended solar panels are 4.4v to 6vDO NOT EXCEED OR BOARD MAY BE DAMAGED
When an SD card in you can not upload software in Arduino IDE since the SD card uses IO2 as CS, the SD card must be removed when uploading a new sketch.
On Version 20200415, When using GPS the SIM7000G(GPIO4)/SIM7070G(GPIO5)(Physical pin number 48) needs to be set to HIGH to enable the antenna modem.sendAT("+CGPIO=0,48,1,1"); once finished the pin can be set LOW modem.sendAT("+CGPIO=0,48,1,0"); to prevent power leaking to the GPS antenna, This will make help battery life. If using USB or battery life is not a concern, it can be left HIGH.
If you are unable to access the network, please try <examples/Arduino_NetworkTest>, which will test the network connection. There are also binary files in the firmware directory; you can use the Flash Download Tools to download.
How to change the connection method?

For example, the Arduino_TinyGSM/AllFunctions.ino , you only need to change modem.setNetworkMode(38); to the corresponding number, and your network access speed depends on the carrier of the SIM card you use. Before using it, you can communicate with the operator of your SIM card.
The effect is as follows:

11. The initial network registration may be slow. Please be patient. You can configure the locked band as shown in the following figure.
